TFM offers Inconel 713C Powder (Alloy 713C, N06625), which is ideal for 3D printing applications. As the additive manufacturing industry continues to evolve, our range of additive manufacturing powder products will expand accordingly.

Inconel 713C Powder Overview

Inconel 713C (Alloy 713C, N06625) Powder is a nickel-chromium-based, precipitation-hardening cast alloy. Known for its remarkable strength, even at elevated temperatures up to 1800°F (980°C), it offers excellent castability, oxidation resistance, and protection against thermal fatigue. Thanks to its high-temperature durability and ductility, Inconel 713C is frequently used in aerospace and industrial applications, such as vanes and blades for jet engines, guide vanes for turbines, press forging dies, and extrusion dies.

Applications of Inconel 713C Powder

Forging

Despite being a cast alloy, Inconel 713C poses significant challenges in forging due to the precipitation elements. These elements require a high temperature solution treatment before forging, which is done at temperatures between 2200°F and 1900°F (1205°C to 1040°C). The alloy’s strength and ductility at high temperatures make hot working difficult, requiring specialized techniques.

Heat Treatment

While Inconel 713C is commonly used in the as-cast condition, heat treatment can enhance its stress rupture life. A solution treatment at 2150°F (1175°C) for two hours, followed by air cooling, can increase performance. For optimum stress properties, a stabilizing treatment at 1700°F (925°C) for 16 hours is recommended. Precipitation treatment between 1470°F and 1650°F (800°C to 900°C) is also beneficial for maintaining high-temperature strength.

Machinability

This alloy is notably difficult to machine due to its high work hardening rate. Precision tools and highly rigid equipment are essential for machining Inconel 713C. Final machining is most effective following the precipitation treatment to minimize work hardening effects.

Weldability

Inconel 713C is generally not considered weldable, but limited success has been reported in welding it to other metals or in low-stress situations. When welding is necessary, Hastelloy W or Inconel filler metal 92 can be used with the gas tungsten arc process.

FAQ

  • Metal powders are fine particles of metals produced through various processes such as atomization, reduction, or electrolysis. They are used in applications like additive manufacturing, powder metallurgy, and coatings.

  • Alloy powders consist of two or more metallic elements combined to enhance properties like strength, corrosion resistance, and ductility, whereas pure metal powders contain only a single element.

  • The shape affects flowability, packing density, and spreadability. Spherical particles are preferred in additive manufacturing due to their superior flow characteristics.

  • Spherical powders are typically produced using gas atomization, where molten metal is atomized into fine droplets that solidify into spherical shapes.

  • Spherical powders offer better flowability and packing density, leading to improved layer uniformity and mechanical properties in 3D-printed components.

  • Factors include particle size distribution, shape, chemical composition, purity, and production method.

  • Yes, metal powders can pose hazards such as toxicity, reactivity, combustibility, and instability. Proper handling, storage, and safety protocols are essential.

  • In powder metallurgy, metal powders are compacted and sintered to produce components with complex shapes and tailored properties, often with minimal waste.

  • Yes, unused or excess metal powders from manufacturing processes can often be collected, sieved, and reused, provided they meet quality standards.

  • The combination of different metals in alloy powders can enhance properties such as strength, hardness, corrosion resistance, and thermal stability, depending on the application requirements.

  • Spherical alloy powders are used in aerospace, automotive, medical implants, and tooling industries for manufacturing high-performance components via additive manufacturing and powder metallurgy.

Production methods like gas atomization, water atomization, and mechanical milling influence particle size, shape, and purity, which in turn affect the performance of the powders in various applications.
